To round 0.6 to the nearest tenth, we look at the digit in the hundredths place, which is the second digit to the right of the decimal point. In this case, 0.6 can be written as 0.60. The digit in the hundredths place is ‘0’. Since this digit is less than 5, we do not increase the tenths place.
Therefore, when we round 0.6 to the nearest tenth, it remains 0.6.
